1 answer:

3 0

White as system of equations:
a=(3,-2) b=(1-1)
{a=1-1
{(3-2)b=1-1
Solve the equation for a:
{a=0
{(3-2)b=1-1
Solve for B :
a=0
b=0
The possible solution to the system is the ordered pair ( a , b )
Solution:
( a , b )= ( 0 , 0 )
There you have your answer :)

Find the equation of the line passing through the points (5,21) and (-5,-29)

Assoli18 [71]

Answer:

Look below

Step-by-step explanation:

lets have -29 be y2 and -5 be x2

21 - (-)29

5 - (-)5

Subtracting a negative is just adding it so

21 + 29 50
5 + 5 10

50/10

this simplified, is 5/1 or 5

y=5x+b

now we need to find b, so we substitute y and y

x = 5

y = 21

21=5*5=b

5*5 is 25

now we need to get to 21

25 -4 is 21

b = -4

y=5x-4

What is the area of the shaded region and the circle inside?

$r=20,1m+13,2m=33,3m$
$A_1=\pi r^2$
$A_1=33,3^2\pi$
$A_1=1108,89\pi$

What is the area of the circle inside?

$A_2=20,1^2\pi$
$A_2=404,01\pi$

What is the area of the shaded region?

$1108,89\pi -404,01\pi =704,88\pi$
$704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}$

The answer: 2213,32 :)
